Simulation and Validation of Pan Evaporation Rates Using COMSOL Multiphysics® Software

L. J. Matel [1]
[1] Green Streets Infrastructure LLC, Seattle, WA, USA

The four foot diameter class A evaporation pan is used by the scientific community as the standard for determining evaporation rates for a number of purposes. The COMSOL Multiphysics® software provides the necessary tools to adequately develop synthetic estimates of evaporation values for input into hydrologic simulation models and other earth science applications. This paper presents ...

J. Alonso [1], V. Navarro [1], M. Moya [1],
[1] Universidad de Castilla la Mancha, Ciudad Real, Spain

The Geoenvironmental Engineering Group of the University of Castilla-La Mancha is developing a computational tool, M4B, for describing the influence of environmental loads on the deformation behavior of soils and its interaction with building foundations. This tool comprises a set of algorithmic files in text format which can be implemented in COMSOL Multiphysics®. To illustrate the M4B scope, ...

Design of a Heat Trap for Optimal Heat and Current Conduction on Soldering Pads

F. Figueroa [1], P. Aguirre [1],
[1] STW, Sensor Technik Wiedemann GmbH, Kaufbeuren, Germany

This poster presents an evaluation study of a couple of heat trap designs, analyzing the generation of Joule heating and heat dissipation characteristics. Through parametric simulations of the heat traps varying geometries, it is possible to see the generated temperature difference at a constant current. Simulating a soldering process, the heat traps are tested on time dependent studies to see ...

Lamb Waves in Fluid-Loaded Plates

[1]ABB Corporate Research, Baden-Dättwil, Switzerland

Lamb waves are elastic waves propagating in free solid plates. In the case of plates loaded with a fluid, the equations describing these waves have to be modified to include the effects of the fluid. In our work we have tackled this problem using COMSOL Multiphysics®. We have used the two-dimensional plane strain model of the solid mechanics interface to calculate the eigenmodes of the coupled ...

Snap Buckling of a Constrained Photomechanical Switch Driven by Elastic Instability

[1] Hope College, Holland, MI, USA
[2] University of Pittsburgh, Pittsburgh, PA, USA

Photomechanical materials experience strains in response to light of certain wavelengths. These remotely triggered, photo-induced strains lead to large-scale deformations, presenting significant opportunities for wireless actuators and light-driven morphing structures. A large space of possible mechanical behaviors exist for these materials since their response depends on a variety of system ...

Simulation of Thermal Elastohydrodynamic Lubricated (TEHL) Gear Contacts

T. Lohner [1], A. Ziegltrum [1], K. Stahl [1],
[1] Gear Research Centre (FZG), Technical University of Munich (TUM), Garching, Germany

Thermal elastohydrodynamic lubricated (TEHL) contacts occur very frequently in drive technology and thus in gear drives. In this presentation, the implementation of a finite element based TEHL simulation approach for gear contacts in COMSOL Multiphysics® software is shown. The physically based simulation approach used is different to most of the existing TEHL simulations and is required to ...

3D Dynamic Linear Electromagnetic Actuator Modeling and Simulation

O. Craciun[1]
[1]ABB AG, Ladenburg, Germany

Single coil actuators are representing one important component of ABB’s medium voltage reclosers. Their performance is strongly influenced by the considered material properties as well as by the electronic control units’ properties that will power the actuator. Therefore, this paper focuses on electromagnetic actuators modeling and simulation in COMSOL Multiphysics®.

Multiphysics Modeling of Electro-Optic Devices

J. Toney
Srico, Inc.
Columbus, OH

Designers of electro-optic modulators and related devices often use separate tools to study the optical and electrical portions of the device. The flexibility of COMSOL Multiphysics makes it possible to construct unified models of EO phenomena including realistic waveguide profiles and anisotropic material properties. We demonstrate the use of the RF Module to compute both RF and optical ...

[1] Plasma Science and Fusion Center - Massachusetts Institute of Technology, Cambridge, MA, USA

The goal of a tokamak is to use high magnetic fields to contain plasma and produce nuclear fusion that can be used for power generation. MIT’s Plasma Science Fusion Center (PSFC) and collaborators are proposing a machine, the Advanced Divertor eXperiment (ADX) to test new technology for these systems at reactor level heat fluxes and magnetic fields. COMSOL Multiphysics® software is used to ...
